WINDOW MASKING DEVICE FOR RUBBER MOUNTED WINDOWS Filed June 12, 1957nite States aten WINDOW MASKING DEVICE FOR RUBBER MOUNTED WINDOWS Thisinvention relates to a masking device for a rubber mounted window whilespray painting the area about and adjacent said window. As is wellknown, rubber mounted window structures are used in air conditionedtrains, buses, and like structures.

Heretofore in coating or painting, especially spray painting, surfacesadjacent to and about such windows it has been necessary to use maskingtape to cover the windows or portions thereof, especially at the edgesthereof, with masking tape to protect them from being painted during thespraying operation. Also, multi-piece masking devices and maskingdevices comprising complicated fastening means have been used. However,it has been found that the masking means and devices presently utilizedand heretofore applied have not provided a practical nor economicalmeans for arriving at the solution of the problem presently existing inthis art. The use of the heretofore known devices and means for maskingthe rubber mounted windows during the spraying operation is costly andrequires much time, effort and material.

Various types of masking devices for rubber mounted windows have beenintroduced by prior workers in the art for doing away with masking tapesor papers or other selective covering means, and in each of these cases,serious problems such as waste of costly time and material havepresented themselves. Also, the prior art devices have not providedeffectively the desired degree of covering to insure a clean, desirableand workmanlike job.

With the masking device of this invention, I have obviated and havepermanently eliminated the problems set forth, including loss ofvaluable time by high salaried personnel employed in this field andwaste of costly material. The masking device of my invention is capableof being installed to cover the windowwithin a few seconds and, inaddition, provides an effective degree of covering to insure a clear,desirable, and workmanlike job at the completion of the work.

The masking device of my invention comprises a sheet of material havinga shape or configuration of the shape of the rubber mounted window to bemasked, means operatively associated with said sheet for engaging therubber mounting of the window, said engaging means comprising aplurality of plate members which are spaced from and parallel to saidsheet, each of said plate members being individually associated withsaid sheet, means for moving said plate members into engagement with therubber mounting, preferably at spaced apart points of said rubbermounting, and means for fixedly positioning said plate members inengagement with the rubber mounting, said fixedly positioning meansbeing operatively associated with said moving means.

An object of my invention is to provide a window masking device forrubber mounted windows capable of absolutely minimizing the timerequired for masking the window which is not to be painted during aspray painting operation, thereby reducing the labor cost formaskingthevwindow and eifecting a great saving in job cost. 1

Another object of my invention is to provide a window masking device forrubber mounted windows to eliminate the waste of masking tapes which canbe used only once.

Another object of my invention is to provide a window masking device forrubber mounted windows which can be used over and over again.

Other objects and features of my invention will become apparent from thefollowing detailed description which is not intended to be limiting butis set forth here as a preferred embodiment.

Figure 1 is a view in perspective of the masking device mounted over arubber mounted window.

Figure 2 is a view in perspective of the sheet of material of themasking device shown in Figure 1.

Figure 3 is a view in perspective of a sheet of material similar to thatshown in Figures 1 and 2 but for a window larger than that shown inFigure 1.

Figure 4 is a section taken on line 4-4 of Figure 1 in the direction ofthe arrows.

Figure 5 is an exploded view of the portion of the device as seen inFigure 1.

Like numerals designate similar component parts.

More specifically, there is provided a sheet of material 10 preferablyhaving a flange 12 therearound. The sheet 10 has the shape orconfiguration of the window 14 which is to be covered thereby and saidsheet may be of any shape depending upon the shape of the window to becovered thereby. The window 14 is a rubber mounted window, as is clearlyevident from Figure 4. As is well known in the art, a rubber mounting ispositioned in a groove, and the window is fixed therein, as is shown inFigure 4. The rubber mounting 16 comprises a curved portion 18 havingflange members 20, 20 integral therewith and extending therefrom. Sheet10 has therethrough the substantially longitudinal slots 22, 22 whichare adjacent to edge portions, preferably opposite edge portions, ofsaid sheet from which said flange 12 depends. The dimensions of thesheet 10 are such that the sheet 10 extends over the top surface 24 offlange 20, as is clearly shown in Figure 4. A stud member 26, preferablythreaded, extends through each slot 22, and the stud member 26 ismovable in and along each slot 22. Attached to the end of said studmember 26 is plate member 28, for example, as by brazing, in such amanner that plate member 28 is substantially parallel to the sheet 10.Positioned about stud member 26 is a spacer member 30 of such dimensionsthat it is retained between plate member 28 and the surface 32 of sheet10 and that its height is preferably less than the height of flangemember 20 of the rubber mounting 16. Positioned about stud member 26 iswasher member 34 between surface 36 of sheet 10 and the end 38 of studmember 26. Washer member 34 is of such dimensions that it at all timesentirely covers slot 22. Threadedly engaging stud member 26 at theportion thereof extend ing above washer member 34 is the tighteningmeans here shown as a wing nut 40. The plate member 28 may be anyregular shape such as hexagonal, as here shown in Figure 5. The sheet'10 may be of such dimensions that it will extend over the top surface24 of the flange 20 of the rubber mounting 16 or at least to the edge 42of said top surface 24. For a larger window a sheet 44 havingtherethrough the slots 46 positioned as shown in Figure 3 may be used inplace of sheet 10, the window to be covered thereby having the sameconfiguration as shown in Figure 3. Sheet 44 may also have a flange48'therearound.

In using the masking device 50 as shown in the appended drawings, thedevice 50 is so positioned that the sheet 10 covers the window 14 andthe flange 12 is positioned between the rubber flange 20 and the edge ofthe area S to be painted, as clearly shown in Figure 4. Each stud member26 is moved in and along its slot 22 in a direction towards the rubberflange 20 until the edge of the plate 28 engages rubber flange 20, Thewing nut 40 is then tightened against the washer 34. Thereby is themasking device 50 including the sheet fixedly positioned to cover thewindow. The same procedure is followed in utiliZing the masking devicewithout the flange 12. In this case, the bottom surface 32 of sheet'ltlis so positioned that its edge engages the edge 42 of the top surface 24of the rubber flange or that the outer portions thereof adjacent itsedge overlaps the top surface 24 of the rubber flange 2i).

It is obvious that my masking device may be used to cover rubber mountedwindows of different sizes by merely changing the sheet of material toconform with the shape of the window to be masked.

it may also be clearly seen here that construction comprising thethreaded stud member and the wing nut is a preferred embodiment and'thatother similar structures may be utilized.

The sheet material members it) and. 44, as hereinabove set forth, are ofstiff, flexible, and resilient material, such as plastic sheets,aluminum sheets, copper sheets, brass sheets, and the like.

Many changes and alterations'may be made without departing from thespirit and scope of this invention which is set forth in the appendedclaims which are to be construed as broadly as possible in view of theprior art.
